Thank you for your patch. We have it running now for some time and didn't 
observe any crashes.

I have one question left. We want to install the same card in another server 
that is currently running Debian stable with a 2.6.32 kernel. Is this bug also 
present in that version or has it been introduces afterwards? This server is 
used by many people for Internet access, so it would be quite bad if it 
crashes.


Thanks again for your work on the patch.

Greetings,
Maxi
